Abstract

1520918 Rotary photometric analyzers F HOFFMANN-LA ROCHE & CO AG 26 Nov 1975 [29 Nov 1974] 48679/75 Heading G1A In a rotary photometric analyzer, tubular sample holders can be inserted into radial apertures in the rotor, and are investigated by light which passes along the holders to a detector on the rotor axis. The holders are shown in Fig. 7, and comprise a body 24 with a removable cap 25. A reagent can be placed in the body before the cap is attached, and then a sample is placed in the cap using a hollow needle; surface tension prevents contact between the sample and the reagent at this time. The holders are then inserted into the rotor 11, Fig. 2, and the rotor is attached to the analyzer by clips 10. Following rotation to cause preliminary mixing, the rotor is oscillated to produce thorough mixing; the rotor is then rotated, the caps are removed by raising a disc 26, and a lamp 10 is activated. A photo-multiplier 23 is lowered to an axial position, and with the aid of rotor timing signals a photometric measurement is made on each holder. A thermostatically controlled reservoir of water is provided, and on rotation some of the water is forced to occupy a region 16 around the bodies of the holders.
